SHUTTLE.

ac'aeai.

To all whom it may concern:

Be it known that I, ULYssE N. TREMBLEY, a citizen of Canada, residing atLawrence, in the county of Essex and State ofMassachusetts, haveinvented certain new and useful Improvements in Shuttles, of which thefollowing is a specification.

This invention relates to shuttles for looms .and particularly to thetype known as hand threading shuttles.

In the old fashioned suction shuttle, a round porcelain ring was used asa shuttle eye, and this eye wore a long time. With modern types of handthreading or self threading shuttles, it has not been possible to use anendless ring, and other porcelain devices, which have been used, havebeen expensive and dificult to make, while metal parts or parts of othermaterial wear out so rapidly from the friction of the yarn that greatreplacement expense is entailed, and there is also morelikelihood of theyarn wearing a groove and breaking.

My invention is applicable to that class of hand threading shuttleswhich have a bobbin recess with which connects a hole or passage toreceive a shuttle eye or plug usually of substantially cylindrical shapeand of metal. My invention consists principally in so making andpositioning such a plug that the yarn in traveling from the bobbin outthrough the plug or eye, after once being threaded, will come in contactwith only smooth, round surfaces of porcelain or similar material.

It is also arranged that the plug can readily be removed in order toreplace broken or otherwise damaged parts In the drawings, Figure 1 is aplan View of what I will'call the front or forward end of a shuttle,parts being broken away to show the location of my plug. Fig. 2 is anelevation from the right of Fig. 1. Fig. 3 is a plan view of my plugremoved from the shuttle, and also shows the machine screw which Iprefer to use for convenience in removing it from the shuttle. Fig. 4:is an elevation of my plug as from the back. Fig. 5 is a view as fromthe front, and Fig. 6 is a view as from the bottom.

of a plug recess B to receive the bobbin G from which the filling oryarn F is unwound. Krepresents the usual longitudinal groove which runsalong that side of the shuttle where is the outlet of the shuttle eye.

As shown, the bobbin recess'B extends toward the front er forward in theform of a neck 19 which is, however, part of the bobbin recess.Transversly of the shuttle from the side opposite the yarn groove K, Ibore a hole 10 which is preferably substantially cylindrical.

end of hole 10 and the inner edges of groove K to serve as a stop forthe plug which is to be inserted in hole 10. This hole 10 is so boredthat its end cuts the curved wall of yarn groove K about midway thusleaving some wood 12 and 14 to serve as a stop. I

Extending forward from the part 19of the bobbin recess, I cut athreading slot 17 which extends forwardly and downward out I prefer toleave a small amount of woodat 12 and 1 1- between the toward the sideof the shuttle where is the; l

outlet of the shuttle eye, and thence backward substantially parallelwiththe top of the shuttle at 18 until this threading slot enters thehole 10 whereby the yarn can be carried forward and then back into ablysubstantially cylindrical, has a yarn passage 25 which extendslongitudinally of the plug and laterally of the shuttle out through oneend which I will call the outlet shown as extending diagonally downward:and outward and recess 30 may be considered part of it. p p M Plug H istrimmed down at 72 so as to leave room for the yarn to pass between 1 itand the inside of hole, through. the slots.

this T3 at the oatlet end cl: the plug 10 as it slips such is alsoslightly shorter than the other end 74 to allow the yarn to pass intoslot 33.

It is evident that instead of trimming down the plug at 72, and insteadof making the side 73 of the outlet end somewhat shorter than the otherside, the wood of the shuttle could be cut away to permit the yarn topass, but in practice, it is easier to shape the plug than it is toshape the wood.

The; portion of wood 14 which is left at the bottom under the cut awaypart 13 at the end of hole 10, preferably projects up- Y. ward above thelower part of side 7 3 and helpsto prevent the yarn from unthreading byslipping down from passage back through ventical'outle't slot 33 andinto plug s1Qt-31.-

To serve as guides or bearings for the yarn as it passes from the bobbinout through the shuttle ,eyedevice, I use porcelain pins each of whichis driven through a pin hole in one part of the shell, and into anotherhole i-na part of the shell which is nearly opposite, as shown clearlyin Fig. 8.

The pins 41Qand '40 are positioned close to the outlet of plug H anddriven from the top; through parallel pin holes 51 and 50,

which preferably terminate in dead ends 52 and 53 as they extend intobut not through the shell."

' I prefer to bore small releasing holes 61 and .60-into the deadends 52and 53 of the pin holes, whereby. the pins 41 and 40 may be readilydriven out by inserting a small red and tapping it.' There is lessdanger of the yarn catching as it passes over the small releasing holesthan there would be iffit passed over the end of a pin such as 4Qand 41,which had not been carefully smoothed.- As shown in Fig. 8, pins 40 and41 need not'accurately fit pin holes 50 and 5-1 and their ends need notbe smooth but may be left rough as they are protected by the dead ends52 and 53 anpl at their other ends by the wood on the inside of the plughole 10. My porcelain pins need not be accurately made and need not fitinto the pin .holes closely, although I prefer to drive themin, as whenthe plug is in place in the plug hole .10, the end or ends of the pinholes 50 an'd51 are closed by the material in which plug hole 10 ismade, so that 4; thepins cannot get out.

A" passage is therefor left between pins 41 and40 into the tubularinside part 25 of the plug H, and the yarn can enter between these pinsas it passes down through slot 31, trimmed-away part 73, around-end 73and through slot 33jinto yarn passage 25 where it remains.

The pin -42; is placed at such a point that itwill pl'q'ttf-tldo beyondthe cut away part 34- of reeess 30 so that it will'guide the yarn- Ffrom the bobbin in such a mannerthat itwill touch QOj-QtllBIX part andallow it-toturn of plug H and into a dead end which enters but does notpass through the other or top side of the shell. A small releasing hole44 enters this dead end whereby the pin can be readily driven out andits end does not come in contact with the yarn in the threading process.

The plug H may be driven in so as to not quiet touch the wood left at 12and 14, thus leaving space for the yarn to pass, in which case, the end73 may be as long as 74, but I prefer to drive it in so that its longend 74 will rest against the wood at 12 and 14 as shown by the dottedline in Fig. 6. In either case, I prefer to'hold it in position by meansof a pin 16 which is driven down through the wood of the shuttle andinto a hole 15 in the plug. In this way, the yarn can pass from recess30 through threading slots 17, 18, and plug slots 31 and 33 down alongthe trimmed ofi portion 72 and between the shorter outlet end 73 of theplug, and the end of large hole 10 slipping up in between the pins 40and 41, and out through the eye groove or opening 13.

I find it convenient at 20 to thread the end'of plug H which is oppositethe outlet, to receive the threaded shank of a screw 21 whereby this endof the plug can be sunk out of sight and still the plugcan readily beremoved after removing the pin 16 through the medium of screw 21.

The outlet end of plug H is recessed at and 71 to correspond with thecurve of groove 13 to allow the pins 40 and 41 to direct the yarn clearof any metal part.

In Fig. 9, I show a slight modification in which the recess 30 of plug Hand the threading slots 17 and 18 in the wood are the same but the plugslot 82 and outlet slot 83 extend toward thetop instead of toward thebottom so that outlet slot 83 extends out vertically between the pins 40and 41 at the top instead of the bottom. The top end 85 is trimmed offto allow the yarn to pass.

In Fig. 10 I show a square plug T which is arranged for a shuttle withan eye or yarn outlet at the left instead of at the right. This has arecess 90 which corresponds with 30, and plug slots 91 and 92 whichcorrespond with 31 and 33, while the pins 40 and 41 are the same, as isalso the guide pin 93 which corresponds with 42.

I prefer to make the exterior pins 40 and 41, and the interior pin 42 ofthe same size and interchangeable, and it is not necessary that theyshould be of any exact length, as an examination of pin 41 in Fig. 8will indicate. It is merely necessary that they should not project abovethe surface of. the plug so as to interfere with its being pushed intothe plug hole in the wood.

tach pin may fit loosely in its pin hole and its ends may be unfinished,as it is put in place before the plug is inserted in the plug hole 10and when the plug is in place the pins cannot escape from their holesbecause there is a dead end, such as 52 or 53, at one end and the insidesurface of the plug hole, such as 10, prevents their escape in the otherdirection.

It is clean that many other forms of threading slots might be used, andit is clear that in place of theplug, I might use any v shuttle.

form of removable member with a pin or pins held at a point or pointswhere it or they will serve as a bearing for the yarn in a pin hole andagainst the wood of the Where two parallel pins are used, they must beso located that there is a yarn passage and a yarn slot between them.

I so position the open ends of my pin holes that they will come close tothe inside surface of the plug hole and will, therefore, be closed sothat the pin cannot get displaced or shake out. In this way, where it isnecessary for the yarn to pass by the end of the pin, there is little,if anything, for it to catch on except the releasing hole which may bevery small.

As shown in Fig. 9, instead of leaving any wood at 12 and 14 and insteadof making one end of the plug, such as 78, shorter than 74;, I can borethe plug hole clean through the shuttle, as shown at 84, and depend uponholding it in position by means such as pin 16;
